Abstract
Example implementations relate to techniques for refining the microstructure of metallic materials used for additive manufacturing. An example can involve generating a first layer of an integral object using a material with grains structured in a first arrangement. After a threshold duration occurs since generating the first layer, the example can involve applying an external force to the first layer to cause deformations in the first arrangement of grains. The example can further involve generating a second layer coupled to the first layer of the integral object to form a portion of the integral object. Generating the second layer of the integral object causes the material of the first layer to recrystallize new grains to replace grains proximate the deformations. The grains that result from recrystallization are structured in new arrangement that improves the physical and mechanical properties of the layer and subsequent layers collective.
